I wouldn't mind opinions/comparisons on SUPERAntiSpyware as well.
Also, is a dedicated aAnti-spyware necessary if you have one of the anti-virus suites (Norton, Trend, or the ever-so-loved McAfee, etc.). I mean, isn't malware malware? Why distinguish between virus, spyware, trojan, worm, whatever. It's all crap I don't want getting on my machine.
